To all whom tmc/ i] concer/n.;

Beit known citizen of the United States,` residing atSt. Johnsville, in the county of Montgomery and f State of New new and useful lm ovements inA Vacuum Automatic Milking-/laehiines",v o f which the following is a specification.. f i' This invention has relation to autriinatici` longitu irial 4 lfrom passing 'nto the militer 1 from the at'- inventions alfl inosphere.

lo milliers and the same particularly relatesl to improvements upon my ready protected by Patents #878,057 and #878,058.

ln connection-with my improvements L foration 1 0 is herewith describe and illustrate my inven;4 tions as an entirety7 disclosing the many lateand novel lfeatures which have been worked out since the date of mypatents' above mentioned. .r -v y. W My impr vements particularl Areside in the milker proper andare calcu ated to en` able the milk to be more'g'entlyrelieved from,

'the cowsl udderland without unnecessary waste of time. A minor 'improvement is made' in the teat cips, which' will. be described fully hereinater. /v

Figure 1 is an elevational 'view showing'fmy device complete. Fig. 2 is `a view ofthe teat cups assembled as when in use, partly in section. Fig. 3 is a vertical-longitudinal seover'se section of the millier.`

Referring more particularly to thedraw- "ings myinvention is described asfollows: The milker 1 is arranged to be seated sei5 curely u on', the bucket or receptable 2 which receptac e is 4desirably of the 'sl'iapeI 'l-lu's-` trated in Fig. 1 off the drawings. v The milker is screwed into the mouth ofthe receptacle,
